[Swift-devel] Where is latest doc on running Swift on Beagle? Covers OpenMP apps?

[David Kelly]

Yep - I was in the process of migrating the automated SVN jobs to the swift user, but it looks like it wasn't running correctly due to filesystem permissions. I am manually running the update now. It should be updated within 15 minutes or so.
